transparent solar panels

transparent solar panel

Technology in the field of renewable energy is increasingly developed. We know that solar and wind energy are the most widely used around the world. In this case, developing transparent solar panels to be able to place them in windows and extend them through the buildings.

In this article we are going to tell you what transparent solar panels are, their characteristics, advantages and disadvantages and much more.

What are transparent solar panels

Transparent solar panels are a new technology that allows the production of solar energy on a wide variety of transparent surfaces. These panels are designed to be as unobtrusive as possible, making them ideal for use on windows, ceilings and other surfaces that require a clean, modern aesthetic.

This is highly efficient technology, so they can produce a significant amount of power compared to their size. They are also extremely durable and resistant to harsh weather and other environmental hazards. When combined with electrochromic materials, these panels can also adjust the amount of light entering a space, helping to reduce the amount of energy required to light a space during the day.

Among the main characteristics of transparent solar panels we have the following:

  • They absorb light like traditional photovoltaic solar panels, but have no visible components, so there are no bulky panels or wires dangling from the house. They can go completely unnoticed.
  • They are very powerful to take advantage of solar energy, since they can work with any inclination.
  • They can be seen from both sides.
  • They can generate electricity even on cloudy days, which is one of the main characteristics compared to traditional solar panels.
  • They can be embedded when constructing a house or building.

How transparent solar panels work

types of transparent solar panels

These panels are made up of thin layers of glass that allow light to pass through easily, as is the case with traditional glass or windows. Materials such as Indium Tin Oxide (TIO) are used in its manufacture and, of course, the main material is glass.

Currently, glass is one of the most used materials: it is found in everything, from mobile phone screens to skyscrapers. Now, let's imagine what it would be like if this material could be used to generate electricity. In fact, this is what is sought in the future, transparent solar panels that can generate and store energy anywhere with glass.

They work in a similar way to photovoltaic panels. In this sense, they are integrated with a set of semiconductor materials that convert the energy received into electricity.

Advantages of using them

There are many advantages that exist on this type of panels with respect to the traditional ones. Let's see which are the main ones:

  • Transparent solar panels are ideal for installation in metropolitan areas. These areas will benefit the most, as they will be able to use renewable energy without having to heavily modify their buildings.
  • They require less free space for installation.
  • If we compare it with traditional photovoltaic solar panels, its installation cost is slightly lower.
  • They have up to 25 years of operation.
  • Reduces heat from solar radiation.
  • They can generate electricity in shady conditions because they can also use artificial light.
  • They prevent UV rays from affecting people's skin and reduce sun exposure.
  • Energy can be stored in photovoltaic cells.
  • Architects have some leeway to incorporate them into their designs.
  • They limit the use of fossil fuels and therefore reduce pollution in the earth's atmosphere.

Disadvantages

It is clear that every innovative product is going to have its advantages, but also disadvantages. There is nothing revolutionary that does not have any negative aspects. Let's analyze what are the main disadvantages:

  • There are still at least two years to go before we can bring this type of panel to market on a large scale.
  • The current version of the transparent solar panel has an efficiency of 1% and is expected to reach 5% efficiency soon. However, this is quite low, if we compare conventional photovoltaic solar cells with a maximum of 7%.
  • They can contribute to a greater gap between economically fragile countries and developing countries.
  • They require high maintenance as they can easily collect dust.
  • It loses effectiveness as the panels become more transparent.

Other uses

The use of these panels has also spread in the field of agriculture. Here they can be used to cover greenhouse structures, mobile greenhouses and other types of growing structures. By installing transparent solar panels on these structures, farmers can generate renewable energy and reduce their reliance on non-renewable energy sources.

In addition, transparent solar panels also offer benefits for plants. By allowing sunlight to penetrate the grow structure, they can provide natural light for plants, which is beneficial to plant growth and health. They can also help maintain a constant temperature within the structure, creating a more stable growing environment and protecting plants from extreme weather conditions.

Transparent solar panels on windows

One of the latest innovations is called solar windows. The American company New Energy Technologies has developed windows that are used as photovoltaic solar panels. The company has created a liquid paint that can be applied to any transparent surface for use on windows to create transparent solar panels.

Composed of materials such as carbon, hydrogen, nitrogen and oxygen, the coating allows the production of small organic photovoltaic cells. The cladding captures solar energy by absorbing light energy through conductors attached to the window frame.

Thanks to these conductors, energy can be extracted and stored in photovoltaic cells. This power can also be directly connected to devices that consume or provide power. A sun window only blocks UV rays, so it is transparent.

It is a durable coating since its manufacturer guarantees its operation for 25 years. The most interesting thing is that this coating can generate photovoltaic energy not only through sunlight, but also in shady conditions thanks to artificial light. All this is designed to work well with skyscrapers, buildings or any type of housing.

According to those responsible, the invention could be on the market in about two years and would revolutionize energy consumption in many homes that can take advantage of the sunlight that enters through any window in the home.

I hope that with this information you can learn more about transparent solar panels and their characteristics.
